Pepto-Bismol contains bismuth subsalicylate, and it's possible to extract the bismuth from it and use it to grow metal crystals. Man wakes up from surgery speaking fluent Spanish despite only knowing ...

Chemical etching (also called photochemical etching, photo etching, or chemical milling) is a precision manufacturing method used to produce intricate metal components without the mechanical stresses ...

Abstract: We demonstrate a single-feed planar antenna capable of independently reconfiguring its operating frequency, radiation pattern, and polarization using stretchable, encapsulated liquid-metal ...

Abstract: In this communication, a novel pattern and beamwidth reconfigurable cylindrical dielectric resonator antenna (CDRA) is proposed. The pattern reconfigurable structure is achieved by a pair of ...
